Took the tires to a Pep Boys and had them install, there is a guy here in SA that's known as the best wheel guy in town and works there no scratches on chrome A-molds and gently puts them on. Paid another $100.00 for mounting/balance and chrome valve stems.
If you go to the discount tire direct site they can quote install prices on line.
I went 285/40ZR-17 on fronts vs 275/40ZR-17
right now they have a promotion a set of four you get a $75.00 Visa Card
